Product interface: square mouth and round head

Product number: QS 1702

Product type: digital optical cable

QS 1702 is an optical fiber audio line. This QS model is a model that Akihabara's e-commerce department is looking for manufacturers to process themselves. Although it has increased, it is far from the quality of Akihabara Q series and QB series.

Q series and QB series are produced by Akihabara factory headquarters. The quality is relatively better and the testing requirements are more stringent.

In fact, many QS series can't pass the test, which is basically equivalent to three products without OEM.

It is better to buy QB 135 than QS- 1702. Last time our company compared the equipment test, QS 1702 was very noisy.
